UNITED. scrarns PATENT OFFI nni-tar JOHN car-matron, or LOWDEN, IOWA.

' MOTOR-STARTER.

To all whOm it may concern:

-Be known that I, AL ERT J. CHARIrroN, a citizen of the UnitedStates', anda resident of Lowden, in the county of Cedar and State of Iowa, have invented an Improved Motor- Starter, of which the following is a' specification. p I

. My invention is an improvement in that class of motor starters in which, a spiral member coacts witha-nother, one being rota-.

or rectilinear ad-' table, so that by sliding justment of one of the members, the other one is rotated, with the efi'ectofimparting rotation to the motor shaft.

y The details of construction, combination, and operation of parts are as hereinafter'deof a portion of the apparatus. Figsi 3 and 4- are different side views of one end of the bafliingpin or device-which is directly connected with the motor shaft for rotating itf.

5 is an end view of the spirally grooved sleeve connected with the motor sha t.

The movable parts -of the apparatus are attached to, and support-ed upon, an L- shaped skeleton frame W,.whioh is,.in practice, arranged horizontally and attached to the motor by screwsinserted at 2. A hand Fig.

. lever Eis keyed on a transverse shaft F arranged in bearings ]z, and a crank arm 9 is keyed to such shaft at f. The said crank arm 1s connected at m, by a link T, with a curved rod S which is adapted to slide in j and m and whose outer-end is attached to the baffling pin B -see Fig. 2. I By shifting the lever. E, or pulling it to? ward the operator. in the direction indicated by the arrow in Fig. 1, the bafiiing pin will obviously be IflOVed-d-Gfi dit is this movement which guides journaled/at K in the frame V, and in .alinement with said shaftis a short shaft 25 which is adapted to slide in a bearing 92. in frame \V. The opposed ends of the two shafts V and t anb provided with members adapted. to

form a, friction clutch L, the hubs of the effects the desired rotation p of the motor shaft B. The latter is; shown Specification of Letters Patent. Patented 1360.17, 1912. Application filed septcmher as, 191;. Serial No. 650,990. 4 v

clutch members being secured to the ,respective shafts by. pins inserted at U and u. 7 A sleeve A, having, interiorly, grooves, is secured bya pinQZ to the outer en'dof thestulfshaft tan'd in al'inementtherewith. The baffling pin B is provided spiral at its inner end with opposite projections;

formed of rollers b journaled on a transverse pin d. The pin B is in alinement with the sleeve A and the rollers .b a-re adapted to ride in the spiral groove of thel'atte'r. The outer-portion of said pin is provided with a cylindrical enlargement,and the whole, ex-

cept the reduced. head shown in Fig. 2, is rn C which is provided on closed by a casing its upper side with atubular e'grtension 0 having a removable cap which permits the convenient insertion of a lubricant. The sleeve C thus serves not o'n'ly as a holder for lubricant, but as a means for excludingdust and dirt from the spirally grooved hearing.

I The outer end of the slidable, curved rod v S, before described, is attached to the bathing pin at Y and secured by means-of a nut, as

shown.

. It is obvious that, by pulling the lever E the battling pin B will be thrust/into the sleeve A, and the engagement of the rollers with the spiral grooves of the sleeve will cause the latter tomove endwise until the outer cone clutch engageswith the inner or concave member, and then, the end thrust being arrested, the sleeve A will be revolved more or less according to the distance to which the batliing pin is forced into it; and

this rotary motion of the sleeve A being imparted to the stub shaft 1, will be transmitted through the. engaged clutch to themotor shaft-B, which, in this case, represents the ordinary eranlr shaft of a motor. dVhen the. motor is thus started, disengaged or released by reason of the sleeve sliding back sufficiently on the baflling inroiiers Z), which occurs in consequence of the more rapid motion of the crank-shaft B.

What I claim is:

In a mo or starter of the type indicated, the c mbimition with a supporting frame and motor and stub shafts journaled therein in due itlliltlflelli and provided at their meeting ends with engaging members, of a spithe clutch L will-be rally grooved sleeve attached to the stub shaft in alinement therewith, a bafiiing pin nlined with the shaft and having lateral projections adapted to ride in the grooves, a curved slidable rod connected With the head of the baflling pin, and a lever and mecha nism connecting it with said rod for effecting first the engagement of the clutch and then the rotation of the alined shafts, substantially as described.
